Unable to clone layer

-Goal: I am trying to create a script to access a layer on portal and clone it. After cloning it I would like to overwrite a layer in either a SQL database or back in portal.

-Reason: As the original layer updates I would like to run the script to update the copy in which I have view layers created from.

-What I have tried: I have tried a multitude of things, but have not found a way to clone the layer without hitting a type error or a way to save the layer in a SQL DB or portal.

-Here is some code and errors for creating a clone:

source_layer = gis.content.search(source_layer_name, item_type="Feature Layer")[0] temporary_copy = ContentManager.clone_items(source_layer) Traceback (most recent call last): File "<string>", line 1, in <module> TypeError: clone_items() missing 1 required positional argument: 'items' temporary_copy = ContentManager.clone_items(items=source_layer) Traceback (most recent call last): File "<string>", line 1, in <module> TypeError: clone_items() missing 1 required positional argument: 'self'

-For saving the layer I have really only tried publish(), but it doesn't seem to take a layer as an input.

How do you save a layer in portal? in a SQL DB? using arcgis api for python?

-Here is what the entire script I have been working with:

def overwrite_existing_layer(source_layer_name, sql_database, layer_name): try: # Connect to the ArcGIS Portal gis = GIS('pro') portal_dstore = gis.datastore # Retrieve the feature layer you want to clone source_layer = gis.content.search(source_layer_name, item_type="Feature Layer")[0] # Create a temporary copy of the layer or use clone_item() shown above temporary_copy = source_layer.layers[0].query() # Save the temporary copy to overwrite the existing layer in the SQL database temporary_copy.publish() print("Temporary copy overwritten in SQL database.") # Delete the temporary copy # portal_dstore.delete_layers(temporary_copy) # if not temporary_copy.exists: # print("Temporary copy deleted.") print('Finished running script') except Exception as e: # Handle any errors that occur during the process print(f"An error occurred: {str(e)}")

-Any and all advice is appreciated. I'm pretty new to using python within the ArcGIS suite. I have not found the esri documentation very useful so if there is any other recommended resources, those would be appreciated!
